Abstract
A diaphragm or non-return valve is disposed in a supporting wall and includes a diaphragm plug and a valve seat having a passage opening surrounded by a continuous surface for sealing adhesion contact of a sealing lip of the diaphragm plug. The diaphragm plug is made as one piece and is of the same elastic, flexible material as the supporting wall, from which the diaphragm plug is separated along its perimetric edge by slots having a predetermined length. The diaphragm plug and the supporting wall are connected by at least two material bridges provided on opposite sides of the perimetric edge of the diaphragm plug, and the valve seat is configured as a shaped plate locked to the supporting wall in a position coincident with the diaphragm plug by a tightening ring, the valve seat and the tightening ring being engaged by elements passing through at least part of the slots.
